Core-Tray Copper

CO₂ Electroreduction on Gas-Diffusion Cathodes Cast from the Assay Offcuts of One Sulfide Exploration Hole

A paper from the School of Underlying Conditions mills the retained assay offcuts of twenty-one intervals from one copper exploration hole, casts each as a gas-diffusion cathode and reduces CO₂ on it in an alkaline flow cell. Every interval yields multicarbon products, from 53.8 per cent Faradaic efficiency in the chalcocite-bearing supergene zone to 13.5 per cent in the pyrite-rich hypogene zone, a single rubble interval outperforms a commercial copper reference, and the three unrecovered intervals are left uninterpolated.
